I have a 89 300e that when I got in my car to go home tonight the power door locks would not work. The antennae would not go up either. When I got home I found the fuse blown. I changed it only to have it explode in my finger.. I then opened all the doors and it did not blow. I was able to activate the door locks and the antennae went up. I then closed the doors and the fuse blew. I narrowed it down to the front passenger door. 3 doors closed all is well. Close the passenger front..bam the fuse goes. If I gently close the door it is fine but once i close hard enough to latch boom the fuse goes again. I can even press the switch at the door jam and it will not blow the fuse Obviously I have a short ...but where?? HELP!!!

Theres that scrunched up rubber conduit between the hinge pillar and the door itself, in the door jamb. The wires get brittle after time and can either break or just crack and contact something metal, either the hinge pillar or the door.
